Most cases of pink eye go away on their own without treatment. But some types of pink eye can be treated.
When pink eye is caused by infection, it is usually caused by a virus, so antibiotics will not help. Still, pink eye caused by a virus can last several days.
Pink eye caused by an infection with bacteria can be treated with antibiotic eye drops or gels.
Pink eye caused by other problems can be treated with eye drops normally used to treat allergies. These drops will not cure the pink eye, but they can help with itchiness and irritation.
When using eye drops for infection, do not touch your good eye after touching your affected eye, and do not touch the bottle or dropper directly in one eye and then use it in the other. Doing these things can cause the infection to spread from one eye to the other.
